Somethings wrong with my Jet City JCA100h

On Sunday I was playing guitar for about 3 hours or so and then I went to the bathroom and left it on. I was only gone for 1 maybe 2 minutes at most and when I got back the head had no power. No tubes were lighting up. I tried a different outlet and it still didn't work. What could be wrong with it? I've gone many 8 hour sessions since I bought it, could it be the tube or a power supply problem? I'm not too educated when it comes to amps, pretty much just how to set my tones and that's it.

Find out what kind you need and buy several. If it is a bad fuse and it blows again then take it to a tech or exercise your warranty. Also make sure the tubes are seated down nice and snug. But like Raijouta said - fuses usually blow for a reason so there is a good chance there is something else wrong. My first guess would be a power tube came loose.

for the money if you buy from an electronics supplier, you can get those fuses and pay mabye $.20 a piece. i ordered 10 for every step in slo blow and fastblow, however most of you know i have a lot of different amps. those100 or so fuses won't cost you more than $20 and you will never have to do it again if you do it right and always have a backup.

only reason i said this was because i was blowing fuses in an amp and paying $2-$3 for like 3 or 4 of them at radio shack.

likly fuse, as 311 said reseat all tubes and see what happens when you throw a new fuse on and it fires right up or goes pop. lets hope for sound.

Thank you all for your help. It turns out it was a blown fuse. I waited for like almost 2 weeks till I decided to take it apart and try to see what piece I need. I thought I needed the socket or whatever so I took the casing and everything apart and got it out lol. Then I seen this little compartment that was holding the fuses and seen that the one looked like a blown bulb so I took it out and noticed that it came with a spare fuse. Popped it in, hooked it up, turned it on...A big smile on my face. Though I did take the casing off and made myself look like a idiot lol. http://i174.photobucket.com/albums/w92/byakuya_666/2012-04-03092746.jpg
